The Claim
Low-carbohydrate diets lead to small reductions in weight and body mass index (BMI) in adults with a mean baseline BMI of 33.2 kg/m², but these effects decrease after 12 months, suggesting limited long-term efficacy for sustained weight management.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Low-carb diets help people with obesity lose a little weight at first, but the benefits fade after a year, so they might not work well for keeping weight off long-term.
